Hear the Difference

Many audiophiles who prefer their music on-the-go use their iPhones as their audio content source, connecting their DAC directly to the phone or iPad. The role and quality of the cable are important with noticeable improvements in sound quality when using superior cables.

With ddHiFi’s new Nyx Silver series 2.0 OTG cable, you’ll definitely hear the difference.

Nyx Series Silver Shielded Data Cable (vs. 2.0)

The original Nyx MFi09S series used a 1st generation silver shielded wire which used a relatively complex structure of separate shielding for its power supply and data transmission. This greatly helped to reduce noise in devices whose power supplies were susceptible to interference.

The new version 2 Nyx 07 series uses the 2nd generation of silver shielded wire which distributes the power supply and data wires at equal intervals. It also uses imported insulation material with an adjusted-density shielding net with black and white spacing along with an outer insulation layer in accordance with impedance matching. Compared to the 1st gen, the newer 2.0 wire is smaller and more compact.

Easy to Plug and Unplug

The narrow-waisted and wide-mouthed plugs are a further extension of the 2023 ddHiFi design language. The advantage of this unique design is to make the plug holdings firmer when plugging in and pulling out. Moreover, the arched-edge will aid in reducing wire creasing, and the bi-color front and rear cavity structure contributes to a more integrated shielding of the plug.

Supercharged High-current OTG Plug (vs. 2.0)

When using an iPhone with audio decoding devices and high current, it’s common to get a pop-up reminder warning that the device cannot be used due to excessive power requirements. The MFi07S uses Lightning 2.0 which allows more audio dongles to be compatible with iPhone.

Considerable Difference

I just received a new FiiO Q15 DAC/AMP and was connecting it to my iPhone 11 pro using Bluetooth. Numerous articles claimed that the USB-C/Lightning connection was far superior, but with the cables I currently have it did not connect properly. I ordered this cable and WHAT an all around difference from Bluetooth. The sound is crystal clear, and I can hear a dramatic difference in the instrumentation and vocals. I highly recommend this cable if you are trying to connect a Lighting phone/device to any USB-C device. I'm extremely happy with not only this cable but also with Bloom Audio's great service, communications and shipping. Thanks for making my listening experience much better!!!


Very high quality item!

Sometimes cables do matter

I am very much in the “cables don’t change sound unless they are broken.” While I still abide by this, this cable has made significant improvements in sound. I have an iPhone X and a Cayin RU7 DAC. I got a certified lightening to usb-c cable on Amazon. The audio would drop all the time, opening apps would cut out, moving the phone too much even caused issues and halt playback. I got another certified cable and same results. This cable has completely resolved the issue. The previous cables also don’t seem to have provided enough power because the bass response is massively improved as well.

Yeah it’s expensive, but just get it. The build quality is insane as well. And it doesn’t get as hot.

Good Quality iPhone to DAC cable

A lightning connect cable did not accompany my Cayin RU-7 purchase, and I was warned that this DAC pulls a lot of power from the iPhone and the wrong cable can stutter the power from the phone to the DAC. This ddHiFi cable works great and build quality is good. I don’t have another cable to compare the sound, but I’m getting great sound to my IEMs and absolute silence when nothing is playing.
